REVERSIBLE SCREW-DRIVER.

SPECIFICATION formingpart of Letters Patent N0. 236,738, dated January18, 1881.

Application filed September 30, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. Writes, a citizen of the United States,residing at Newton, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement in ReversibleScrew-Drivers, which improvement is fully set forth in the followingspecification and accompanying drawings, in which- Figure 1 represents aview, in perspective, of my invention. Fig. 2 is a sectional elevation.Fig. 3 is a cross-section, and Fig. 4 views showing the invention asadapted to other tools.

This invention relates to certain improvements in that class ofreversible tools having a tool proper pivoted in a bifurcated handle, sothat either end of the tool may be turned to position for use; and ithas for its object to provide an improved means for holding the tool inposition, as more fully hereinafter specified.

In the drawings, Ais the bifurcated handle, holding between its jaws theblade of tools B, which is pivoted, at or near its middle, into thelower ends of the jaws a. The blade B is held rigidly in position bymeans of a sleeve or collar, U, that slides on the lower part of thehandle, and which is prevented from coming entirely off by theprojecting ends of the pivot b, which acts as a stop or rest for thesleeve.

When it becomes necessary to reverse or turn the blade around, thecollar is slid up toward the top of the handle past the slit, thusallowing the blade or tool to be changed; then the sleeve is slid backinto position to hold the tool ready for use.

The pivot may be made removable, so that one handle can be used foravariety of blades or tools, if desired.

It is obvious that the device can be used for a large number of tools ofdifferent kinds where it is desirable to have two sizes of the sameimplement in constant use and at convenient command, or two implementsin the same handle, such as a screw-driver and gimlet combined, when itis necessary to use one tool after the other.

I am aware that a reversible tool pivoted to a handle having a slidingspring-clamp to grasp one end of the tool and hold it in position hasbeen heretofore used, and such I do not claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

As a new article of manufacture, a reversible tool consisting of acylindrical shank provided WVILLIAM ATHERTON WALES.
